FAQs

Should I get all my windows replaced at once?

You don’t have to, especially if you’re on a budget. If you’re only replacing some, it’s a good idea to get all the windows on one side of your property replaced at the same time, so they all look the same. Be aware, obviously, huge savings could be had by having a number of windows replaced at the same time.

What is the Window Energy Rating (WER)?

The energy efficiency of windows is measured using ratings, varying from A, the most efficient, to G, the least efficient. This scheme is run by the British Fenestration Council (BFRC). To comply with Building Regulations you’ll need windows of energy efficiency at least level C.

how much is double glazing?

Double glazed windows are one of the most popular window options for home and property owners in the United Kingdom and reasonably so. They are able to offer a wide range of benefits to home owners which includes being energy efficient, reducing the build up of condensation on windows and black mould growth, significantly reducing background noise for a better relaxation or night rest, increasing the value of your property as well as adding to the aesthetic appeal of your home. So if you’ve decided to lay your hands on a double glazed window, you’d probably also like to know how much it’s going to cost. Well, providing a simple and accurate answer to the question of double glazing window cost is almost impossible as there are so many factors that influences the price including the materials and style.

Several suppliers usually provide the list of their double glazing windows on their websites, however these prices are only for basic off the shelf window and most often without the installation cost. Furthermore, if you require some special features to your double glazed window, then this will also tell on the total cost of the window.

So how much will a double glazing window cost? The cost of a double glazing window usually ranges between £100 to £3,200 per window, depending on the available options.

To have a more accurate estimate of the cost of a double glazing window, you’ll need a obtain a survey from a double glazing installer who can take into account any possible complications that may arise when installing your windows while also giving an advise on the most suitable window style for your property.

Do I need to stay at home while my windows are being replaced?

Most installers will not need you to be at home while they are fitting your windows. It is a good idea to be present though, just in case they have any questions for you and perhaps for your own peace of mind. If you cannot be there, you will need to arrange access to the property and/or agree securing the property at the end of the day.
